IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS

1. This document contains important safety and operating instructions for the

NTN7209 (model AA16740) charger.

2. Before using the battery charger, read all the instructions and cautionary markings

on (1) battery charger, (2) battery, and (3) radio using battery.

3.

4. Do not expose the charger to rain or snow.

5. Use of an attachment not recommended or sold by Motorola may result in a risk of

fire, electric shock, or injury to persons.

6. To reduce risk of damage to the electric plug and cord, pull by the plug rather than

the cord when disconnecting the charger.

7. Make sure the cord is located so that it will not be stepped on, tripped over, or

subjected to damage or stress.

8. An extension cord should not be used unless absolutely necessary. Use of an

improper extension cord could result in a risk of fire and electric shock. If an

extension cord must be used, make sure:

a. that the pins on the plug of the extension cord are the same number, size,

and shape as those on the plug of the charger;

b. that the extension cord is properly wired and in good electrical condition; and,

c. that the cord size is 18AWG for lengths up to 100 feet and 16AWG for lengths

up to 150 feet.

9. Do not operate the charger with damaged cord or plug - replace them immediately.

10. Do not operate the charger if it has received a sharp blow, has been dropped, or

damaged in any way; take it to a qualified service technician.

11. Do not disassemble the charger; take it to a qualified service technician when

service or repair is required. Incorrect reassembly may result in a risk of electric

shock or fire.

12.

The fuse should only be replaced by type 5MF 1.6A, 250V, manufacturer BEL.

13. Maximum ambient temperature around the power supply must not exceed 40°C

(104°F).

CAUTION

To reduce risk of injury, charge only Motorola nickel-cadmium, or

nickel-metal hydride rechargeable batteries listed for charger NTN7209

(model AA16740). Other types of batteries may burst, causing personal

injury and damage.

14. This charger is suitable for different rated voltages. The switch-over to the

corresponding rated voltage, which belongs to the specific rated appliance, is done

automatically in the appliance.

15. The output power from the supply must not exceed the rating given on the charger.

16. The circuit wiring of the power supply is made in such a way that components like

capacitors are positioned in front of the power supply fuse. Therefore, the unit must

be protected by a fuse in the installation system.

17. This power supply is a table model and is used for battery charging. It is certified

according to the relevant safety standards UL 1012, CAN/CSA-C22.2 No. 223-

M91, VDE 0700 Part 1 and VDE 0700 Part 29.

18. The disconnection from the line voltage is made by pulling the main plug.

19. To reduce risk of electric shock, unplug the charger from the outlet before attempting

any maintenance or cleaning. Turning off the controls will not reduce the risk.

GROUNDING AND AC POWER

CORD CONNECTION INSTRUCTIONS

The charger should be grounded to reduce the risk of electrical shock. The charger is

equipped with an electrical cord having an equipment-grounding conductor and a

grounding plug. The plug must be plugged into an outlet that is properly installed and

grounded in accordance with all local codes and ordinances.

WARNING

Never alter the AC cord or plug provided. If it will not fit the outlet, have

a proper outlet installed by a qualified electrician. An improper

connection can result in the risk of an electrical shock.

MAINTENANCE AND

OPERATING INSTRUCTIONS

1. Plug the ac line cord into the proper ac receptacle (see the table on the following

page for the ac voltage and line cord compatibility). The battery charger performs a

power-up self-test. During the self-test, the LED charging indicators illuminate,

alternating red then green, three times to indicate a successful power-up

sequence.

2. Place the battery, or radio with battery, into the charger pocket. The red LED will

light, which indicates that the battery is being rapid charged. When rapid charging

is complete, the red LED will go out and the green LED will illuminate. An

illuminated green LED indicates that the battery is being slow charged.

3. Several different LED conditions can occur. The following list describes a lighted

LED, and the corresponding condition.

a. alternate red, then green (three times) — indicates a successful power-up

sequence, or the recovery from a fault condition.

b. constant red — indicates the battery is being rapid charged.

c. constant green — indicates that the battery is being slow charged.

d. flashing red and/or green LED — indicates a battery fault condition. If a fault

condition exists:

(1) pull the ac line plug from the ac receptacle to remove power from the

charger;

(2) remove the battery from the charger, and clean the charging contacts on

the charger and on the battery;

(3) restore power to the battery charger; and

(4) reinsert the battery into the charger. If the battery still exhibits a fault

condition, replace the battery. The faulty battery can be checked by an

authorized Motorola facility.

NOTE

Batteries will rapid charge within the temperature window 10°C to

40°C. Outside of that temperature window, the battery will be slow

charged and the green LED will flash.
